While probing for the command line limit AC_LIBTOOL_SYS_MAX_CMD_LEN
can provoke warnings from the shell on FreeBSD. I'm not 100% certain
whether the patch below is the best way to suppress that, but it seems
to work for me on various systems.
* libtool.m4 (AC_LIBTOOL_SYS_MAX_CMD_LEN): Send "test"
warnings to /dev/null, helps FreeBSD and maybe others.
